New here but learning slowly. Advice appreciated

[Albuquerque]

I choose to find humor in the mind of the MLCer whenever possible. Helps to counterbalance the pain. In a recent email, I continued with my new approach of emailing facts about D as necessary as well as including one or two items that he might be interested in. The last email I sent him, I mentioned that I had bought D a new mask and snorkel and while in the store, got some information on signing up for a NAUI refresher SCUBA course. For those of you who may not know, there are various organizations that certify SCUBA divers and PADI and NAUI are two types. My H is a certified PADI divemaster. I didn't even really think about that when I sent the email. He emails me back that he was OK with the rest of the email but, and I quote

"NAUI?! WTF?! As a PADI divemaster, one of the things that I *can* do is teach the refresher course. But all things considered, it probably would be easier to go with someone that already has a pool and has actually been in the water at some point during the last four months. But NAUI?!? You shame me."

I know he meant this mostly in jest but I found it totally hilarious. There is a rivalry between the two organizations that I kind of forgot about. But I found it TOTALLY weird that he would even SUGGEST that I do the refresher course with him (which it seemed like he was suggesting). I should have said WTF?! You haven't wanted to spend ANY significant time with me in the last friggin 9 months, why in the hell would I even THINK about asking you to help me do a refresher course?! LOL! All I can do is laugh. MLC=confusion indeed.
What I DID say is that I was MORE than happy to have a PADI divemaster do my refresher course, and left it at that.
